into electricity than vertical axis wind turbines. For this reason they have become dominant in the commercial utilityscale wind power market. However, small vertical axis wind turbines are more suited to urban areas as they have a low noise level and because of the reduced risk associated with their slower rates of rotation.

Apr 08, 2013· A Caltech researcher thinks arrays of tiny wind turbines could produce cheaper power than big ones. The approach, however, faces some challenges. Verticalaxis wind turbines aren't as efficient as conventional ones—half of the time the blades are actually moving against the wind, rather than generating the lift needed spin a generator.

Power Coefficient It's an Efficiency. I would like to call it (and some people do) overall turbine system efficiency. The wind power industry often calls it the Power Coefficient, and gives it the symbol Cp.. The technical and product literature is now full of it (the term Cp I mean), so Power Coefficient it shall be for the rest of this page.
